Brief explanation

This abstract describes a computer system that has a user interface with different elements, such as buttons or menus, and a background element. When the system detects an input from the user, it determines whether the input is directed towards one of the user interface elements or the background element.

Universal serial bus time synchronization (18334394)

Inventor John H. Kelm

Brief explanation

This abstract describes an apparatus that includes various components, a distributed timebase circuit, an interface, and a Time Synchronization Circuit (TSC). The purpose of this apparatus is to provide a consistent time measurement across different components by synchronizing their local timebases to a global timebase. 

The interface of the apparatus is designed to be connected to one or more devices, and any transmissions on the interface are divided into multiple frames. The time on the interface is determined based on a frame number that identifies a specific frame.

Electronic Devices with Power Boosting for High Frequency Communication (18184555)

Inventor Zdravko Boos

Brief explanation

This abstract describes an electronic device that includes wireless circuitry with light sources, photodiodes, a resonating element, and a common gate amplifier (CGA). The device can operate in transmit and receive modes. 

In the transmit mode, the photodiodes use optical local oscillators to generate equal portions of an antenna current. This current is then amplified by the CGA and transmitted through the resonating element.

In the receive mode, the resonating element generates an antenna current, which is amplified by the CGA. The amplified current is then passed to the photodiodes.

To boost power, multiple photodiodes are connected to the amplifier in a current sharing configuration. The amplifier has a wide bandwidth, performs impedance matching between the resonating element and the photodiodes, and isolates the photodiodes from antenna mismatch.

Additionally, the antenna can be integrated into a phased antenna array to further increase power.

Inventor Digvijay A. Jadhav

Brief explanation

The abstract describes a method for monitoring and controlling the power usage of radio frequency (RF) emitting components in a mobile device to regulate the amount of RF exposure. By tracking and modifying power usage over time, the mobile device can control the average RF exposure within a specific time period. The mobile device periodically calculates updated averages of RF transmissions based on data received from its components, and compares these averages to predetermined power limits.

Peak detection may be performed to detect the range. Using standard-compliant transmit waveforms to also perform spatial ranging may allow the communications circuitry to avoid dedicated radar circuitry while also minimizing impact to the transfer of the data.

SYSTEM AND METHOD FOR NETWORK DYNAMIC ON/OFF SIGNALING (18131742)

Inventor Sigen YE

Brief explanation

The abstract describes a method for a base station in a wireless communication system to enter a power-saving mode called "dynamic off period." This mode suspends downlink transmission and/or uplink reception. The abstract suggests two approaches for notifying a user equipment (UE) about this mode. In the first approach, the DCI message is modified to include new values that indicate the different power-saving states of the base station. In the second approach, a new notification message is defined. The notification signal may also include specific parameters related to the cell and beam, as well as an application delay that determines when the dynamic off period will start.

Abstract

An approach is described for a dynamic off period of a base station within a wireless communication environment and a process for notifying a UE of the same. In a first scenario, the DCI message is modified with newly-defined values indicative of the different power saving states (i.e., “dynamic off states”) of the base station. These power saving states may defined as suspending one or both of downlink transmission and uplink reception. In another scenario, a new notification message is defined. In either case, the notification signal may also include cell and/or beam specific parameters as well as an application delay that defines a start time of the dynamic off period.

Retransmission of MsgB in Two-Step Random Access Procedure (18334933)

Inventor Chunhai Yao

Brief explanation

This abstract describes a method for a wireless device to transmit a signal to a base station and then wait for a response. If the device does not receive a response, it will continue to monitor for any retransmissions of the response message. These retransmissions may be identified by a transmission number or by being partially scrambled using a unique identifier. The monitoring window may be extended to include these retransmissions. The retransmissions may contain the same information as the initial transmission or a reduced set of information as devices acknowledge successful receipt of their respective data.

Abstract

A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.

Electronic Devices with Adaptive Device-to-Device Communication Switching (18328621)

Inventor Jan K. Ellenbeck

Brief explanation

This abstract describes a communications network that includes a relay device. The relay device receives signals from other devices in a device-to-device (D2D) communication. The relay device can operate in two modes: ad hoc mode and organized mode. In the ad hoc mode, the relay device consumes low power and receives a small number of messages from a few transmitting devices. In the organized mode, the relay device consumes high power and receives many messages from multiple transmitting devices.

The receiver on the relay device can switch between the ad hoc mode and the organized mode based on specific criteria. When a first criterion is met, the receiver transitions from the ad hoc mode to the organized mode. When a second switching criterion is met, the receiver transitions from the organized mode back to the ad hoc mode.

This switching between modes allows the relay device to balance the load of communications and power consumption. It is particularly useful for relaying emergency messages received over D2D signals, as these messages may arrive infrequently or in clusters due to unexpected events.

Abstract

A communications network may include a relay device that receives device-to-device (D2D) signals. In an ad hoc mode, the relay may consume relatively little power while receiving relatively few messages from relatively few transmitting devices in the D2D signals. In an organized mode, the device may consume relatively high power while receiving many messages from many transmitting devices in the D2D signals. A receiver on the device may transition from the ad hoc mode to the organized mode in response to a first criterion and may transition from the organized mode to the ad hoc mode in response to a second switching criterion. This may allow the device to balance communications load and power consumption while relaying messages such as emergency messages received over D2D signals given that the signals may arrive rarely or in clusters due to an unforeseen event.
